• 5 kW sealed underwater permanent magnet generator which is gearless driven by three blade rotor.

• Output up to 600 V chaotic AC, necessary rectifier-inverter in line.

• Output velocity dependent.

• Power curve – power as function to velocity .5 kW @ 3.1 m/sec.

• Cost-efficient, renewable base load solution

• Flow velocities highest in center decreasingtowards side walls. Require fine tuning ofindividual turbine in array varying sweep dia.

• Wake of individual turbine interfering witheach other. Application of diffusers required.

• Installation structure needs to behydrologically optimized to reduceturbulence – use rounded steel.

• Blockage leading to level rise upstream ofproject. Floating model with reduced no ofturbines per array to be adopted forextraction of maximum power out of canalwith minimal level rise.

Technical Optimization

Existing steel structure

Possible structure with diffusor

Future of Distributed Generation

31/01/2018 10

Use existing infrastructure and addgeneration capacity at costs 3 to 5 U$ ctper kWh (depending on flow)

• Tail races of existing hydropowerplants

• Cooling canals of thermal powerplants or chemical plants

• Irrigation canals with velocity >= 2m/s

• Natural rivers with more than 3 mdepth (in dry season) and >= 1.5 m/saverage velocity mainly for ruralelectrification (higher costs for offgrid installations)
